This will allow to deMpegEncContextize the LJPEG encoder.

It only needs PutBitContext from it, so pass that directly.

MpegEncContext.aspect_ratio_info is never set for mjpeg, so this was
never written before.

This code was originally added in
5f1948111a to h263 to set decoded frame
pts to some random numbers (removed in
a1c5cc429d) and then cargo culted to other
decoders.

The code is left in h263dec for now, since some part of the decoder
(apparently OBMC) relies on the specific previous frame to be reused.

This has already been done in eb066a4ce9e82cddb8f5af574804aa9889450b34,
but the number of frames produced from that file changed due to
timestamps changes since then.

This will allow removing the hacks where each decoder sets
current_picture_ptr on its own.

It is only called from one place in mpegvideo.c now. Also remove the
remove_current parameter, which is always 1.

It is not called from outside of mpegvideo.c anymore.

It is used for encoding only.

It is encoding-only, frame threading is not used for encoding.

The mmxext optimizations should be at least equally fast if available and
amd3dnow optimizations are being deprecated. Thus the former should
override the latter, not the other way around.
